Spring is here, and Cho and her uncle would like to go fishing for the weekend in Washington. Cho could either go to the river in town where anyone can fish without a permit, or she could drive up to a stream located on her family's property in the countryside to fish. Assume that, no matter where people fish, all of the fish that are caught would be kept (that is, there is no "catch and release" policy).

The fish in the private stream are considered(Rival in consumption/ nonrival in consumption) and (Excludable/ nonexcludable) whereas the fish in the river are(Rival in consumption/ nonrival in consumption) and (Excludable/ nonexcludable) . In other words, the fish in the private stream are an example of (A public good/ private good/ club good/ common resource) , and the fish in the river are an example of (A public good/ private good/ club good/ common resource). Fishing in the river will likely lead to( Tragedy of the commons/ adverse selection / the free-rider problem) because of which of the following reasons?

A. Nobody will enjoy fishing because of the lack of private contributions to the maintenance of the river.

B. Anyone can fish in the river, and one person's fishing activity decreases the ability of someone else to fish with success.

C. All fishermen will choose to fish in the river because of the limited access to the stream.

D, All fishermen will choose to fish in the stream believing that there are more fish there.
